FLUSi-HNG APPARATUS FOR WATER-CLIOSETS.

SPECIFICATION forming` part of Letters Patent No. 745,823, dated December 1, 1903.

Application led February 17,1902. Serial No. 94,438. (No'inodel.)

To L7/Z 'whom t may concern:

Be it known that I, WILLTAM U. Garrrrrns, a citizen of the United States, residing in the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, havevinvented certain new and useful Improvements in Flushing Apparatus for Water-Closets, of which the following is a specification.

My invention relates to the particular type of flushing apparatus in which in connection with the flush tank and the outlet pipe leading from said tank to the structure to be flushed, is employed a siphon mounted within said tank.

It is the object of my invention to arrange the siphon in such manner and to provide it with operating devices of such character as to produce a very useful and efficient apparatus.

In the accompanying drawings I illustrate a good form or embodiment of my invention. Many variations in construction and arrangement may, however, be employed without departure from the spirit of invention.

In the accompanying drawings,

Figure 1 is a view in central vertical sectional elevation of aflush tank containing a siphon, a closet, the pipe through which watery passes from the tank to the closet7 and the associated working parts of the apparatus, the parts being shown in the position they occupy when the closet is not in use.

Figure 2 is a view of the siphon and adjacent parts, showing the relation of the lever to the cam during the time the motion transmitting rod remains elevated while the weight of a person rests upon the closet seat.

Similar letters of reference indicate corresponding parts.

The closet a of any ordinary and preferred character, having a hinged seat b, is connected in any preferred manner through the pipe c with the tank d.

The supply pipe e of the tank is equipped with any suitable valve f by a float g, mounted on a suitable arm such as h.

The parts of the apparatus so far described are not novel with me.

The upper. end of the pipe c or a connection thereof extends through the bottom of the tank CZ and is suitably packed to prevent the escape of liquid. The upwardly extending lip at the mouth or port of said pipe is encircled by a ange which rests upon the oor of the tank. A suitable packing ring encircles said lip and rests on said flange.

. m is a movable siphon structure hingedly connected through a lug it or otherwise to a suitable lateral extension connected to the upper end of the pipe c.

Obviouslythe hinge connection between 6o the siphon and a fixed portion of the tank may be located at any point which the form and arrangement of tank and siphon employed mayrender desirable.

The lower end of the longer leg of the siphon rests, when the siphon is in its normally closed position as in the drawing, upon the packing ring upon the upper face of the Iiange i.

The pipe c, as will be understood, consti- 7o tutes in effect a continuation of the longer leg of the siphon.

o is acam mounted upon that face of the shorter leg of the siphon m which is farthest from the hinged connection of the siphon with the pipe c.

p is a lever conveniently pivoted upon the bracket q at the edge of the tank, and at itsv inner end provided with a roller r adapted to travel up and down in Contact with the face 8o of the cam o.

s is an extension of the seat b, provided, if necessary, with a weight t.

j is a motion-transmitting rod, pivotally conlnected to the outer end of the lever p,-and` normally depending in the position shown. Said motion transmitting rod conveniently extends through a suitable guide w, and may be provided with a stay pin or enlargement lo which by encounter with said guide limits the 9o descent of said rod.

The operation of the apparatus will be readily understood.

The weight t normally maintains the hinged seat b in the elevated position shown. When the weight of an occupant rests upon said seat its consequent depression will, of course, occasion the elevation of the extension s, which extension, in rising, encounters the end of the motion-transmitting rod j and occasions roo its elevation.

The elevation of the rod j occasions the tilting movement of the lever p, in which movement, of course, the outer end of the lever rises and the inner end descends.

In the descent of the inner end of said lever, the roller r, riding downward across the face of the cam o, occasions the tilting of the Siphon upon its hinge.

The arrangement is manifestly such that the force exerted by the roller r upon the siphon through the cam is applied upon that side of the Siphon opposite the hinge, and consequently the ready tilting of the siphon is assured.

In the tilting movement of the Siphon the lower end of the longer leg of the Siphon is transiently elevated away from the mouth or inlet port of the outlet pipe, said tilting movement, first rearwardly, and then, by gravity, back to normal position, occurring in the period of time during which the roller r is passing from the upper end, of the cam o to its lower end.

In such period, however, the mass of water in the tank has access to the mouth of the pipe c, and a considerable quantity descends intosaid pipe, with the result that, so soon as the movable siphon returns to normal position, a siphoning action is established through the Siphon and pipe, which continues until the Water level in the tank descends to the open end of the shorter leg of the siphon.

During the time the weight of the occupant rests upon the seat b, the rodj is maintained elevated, the lever h tilted, and the roller r at the lower end of the cam 0.

After the first siphoning action referred to, in which the water of the tank is when the weight of-the occupant Iirst rests upon the seat, discharged from the tank in a fiushing operation, -the water continues to flow through the supply pipe e into and accumulate in the tank.

Upon the subsequent removal of the weight of the occupant from the seat Z9, said seat automatically rises to its normal position,

being that shown in the drawing, whereupon the Weight of the arm j depresses the outer and elevates the inner end of the lever p, causing the roller o" to ride upward over the face of the cam o until it reaches the normal position shown in Fig. l of the drawings, thus causing a second movement of the siphon upon its hinge.

In such second tilting of the siphon upon its hinge, the water which has accumulated in the tank subsequent to the flushing operation iirst described, will, in the momentary uncovering Vof the mouth of the pipe c, have access to the pipe c, and again, so soon as the siphon is restored to its normal position, there will be a siphoning action established, with the result that the water will be discharged from the tank to the closet.

As will be understood, therefore, my invention in its preferred embodiment, provides an apparatus in which a Siphon is hingedlv mounted within a tank and is caused to be automatically tilted for the establishment of a siphoning action twice in connection with each use of the closet.

Both in the rst flushing operation in which thevroller r descends across the face of the cam, and in the second flushing operation in which it ascends across said face, said roller, in riding to the crest of the cam, forces the, Siphon outwardly and upwardly upon an arc concentric with its hinge pivot; said rollero after reaching and passing along said crest, will, in riding to the foot of the incline of the cam, permit the siphon to return by gravity to its normal position.

My invention may be'applied in many different forms or embodiments without departure from the spirit of my invention.

Having thus described my invention, I claim- 1. In combination with a flush tank having an outlet pipe embodying a port within said tank, a siphon hingedly disposed within said tank in such arrangement that when in one position its longer leg isin communication with said port and when in another position exposes said port so that water from the tank may rush directly thereinto, and means for occasioning the movement of said siphon upon its hinge, said means comprising a cam mounted on the Siphon and beveled in opposite directions, a hinged closet seat having an arm or extension, a pivoted lever mounted upon the ushing tank, a rod depending from said lever, the lower end of which is in proximity to said arm or extension.
